We can undertake SBEMs using the approved DCLG iSBEM or approved Dynamic Simulation software (IES or TAS).

The Simplified Building Energy Model (SBEM) is a software tool used to determine C02 emission rates for new non-domestic buildings in support of the National Calculation Methodology (NCM), the Energy Performance of Buildings Directive (EPBD) and the Green Deal.

Whilst DSM software is only required in ADL2A for complex buildings with atria or demand ventilation, it can be used on all buildings if requested.

This can be an advantage if a Thermal Model for a design overheat analysis or BREEAM compliance is required.

Pricing an SBEM calculation is complex, it is not based on area, but on ‘zones’ of different services and usage; consequently a large warehouse may have few zones and be significantly cheaper than a much smaller small office block with diverse use with many zones.

That’s why we can’t give generic SBEM prices but if you send us your site plans we will give you a quotation by return usually within minutes.

When we issue the ‘as designed’ SBEM, we will also issue the Predicted Energy Performance Certificate which is used for marketing the unfinished or Shell and Core building, free of charge.

On completion of the project the initial ‘as designed’ SBEM calculation is converted up to an ‘as built’ SBEM.

We do not charge for the ‘as built’ SBEM if the building layout is unchanged, all we will need is confirmation of the buildings construction, details of the HVAC plant, the lighting installed and the result of the Air Permeability Test.

We can also issue the ‘on construction’ Energy Performance Certificate if required.

We can assist in calculating construction U values, thermal bridging and thermal mass, to ensure that you get the best SBEM result possible.

A few pounds spent on calculating the actual U value or thermal bridges will improve the SBEM result, reducing dependency on renewables, saving money without even changing the construction.

If you plan to use the same construction specification repeatedly, that saving will be made on all subsequent builds.

We offer a fully co-ordinated service, so if the site has a requirement for energy statements for planning approval or there is a BREEAM requirement, just give us a call and we will explain how HIBEC Ltd will save you time, energy and money.
